-// Mac-specific file watcher implementation based on kqueue.
-// The Linux and Windows versions are able to detect:
-// - file creation/deletion/modification in a watched directory
-// - file creation/deletion/modification for a watched file
-// - modifications to the paths to a watched object that would affect the
-//   object such as renaming/attibute changes etc.
-// The kqueue implementation will handle all of the items in the list above
-// except for detecting modifications to files in a watched directory. It will
-// detect the creation and deletion of files, just not the modification of
-// files. It does however detect the attribute changes that the FSEvents impl
-// would miss.
